Abstract
The present disclosure provides a heat pipe capable of preventing deformation of even a thin container and having excellent heat transfer characteristics by preventing freezing of a working fluid even if the longitudinal direction of the container is set substantially parallel to the direction of gravity in cold regions. A heat pipe includes a container having a tubular shape with both ends sealed, a wick structure stored in the container, and a working fluid sealed in the container, wherein, in at least one of cross sections perpendicular to the longitudinal direction of the container, the wick structure is in contact with the inner surface of the container at two points but both side surfaces of the wick structure are not in contact with any inner surface of the container, and a sintered metal layer is formed on the container inner surface being not in contact with the wick structure.
